What is a Coda?
The term Coda comes from Children of Deaf Adults. It commonly refers to a hearing person who has at least one deaf or hard-of-hearing parent.
Codas have diverse family backgrounds, communication styles, languages, identities, and life experiences. Some use sign language and others do not. This platform approaches those varied experiences without assuming that there is only one way to be a Coda.
